To all whom it may concern:

Be it known that I, THOMAS BENTLEY, a citizen of the United States ofAmerica, and a resident of Hopkinton, in the county of Middlesex andState of Massachusetts, have invented certain new and usefulImprovements in Devices for Preventing Singles in Roving and SimilarFrames, of which the following is a specification.

This invention relates to roving frames and similar apparatus in which aplurality of slivers are led through suitable guides ing rolls andparticularly to the stopping mechanism therefor whereby the operation ofthe frame will be stopped upon the breaking of a sliver.

The object of the present invention is to secure a breakage of theunited slivers in advance of the drawing rolls whenever a sliver hasaccidentally become broken thereby preventing the single unbroken sliverfrom being fed from the drawing rolls.

Heretofore as far as is known whenever a sliver becomes accidentallybroken the stopping mechanism operated by the breakage effects astoppage of the machine and causes the other slivers to be broken butbefore the machine can be stopped on account of the high rate of speedat which it is running a considerable quantity of single unbrokenslivers will be wound upon the bobbin. WVith careless or dishonestoperators this is liable to remain thereon to the injury of the cloth inwhich the product is used. It also interferes with the proper operationof the looms in which it is used.

The purpose of the present invention is to prevent any singles frombeing wound upon the bobbins, this being accomplished by the severing ofthe entire roving ofany afieeted set, thus obliging the operator to passbetween the drawing rolls new slivers to replace the broken ones andproperly unite them with the disconnected ends.

The invention for accomplishing these objects consists in certain novelfeatures of construction and arrangement of parts which will be readilyunderstood by reference to the description of the drawings and to theclaims to be hereinafter given.

Of the drawings: Figure 1 represents a eye 21 in a breai'ing device rearelevation of a portion of a roving or similar frame equipped with adevice embodying the features of this invention. Fig. 2 represents atransverse section on line 22 on Fig. 1, looking toward the right toshow more clearly the means for effecting the oscillation of the feelerand the parts cooperating therewith. Fig. 3 represents a transversesection of the same, the cutting plane of the left side therof being online 33 on Fig. 1, and the right side thereof being on line 22 onFig. 1. Fig. 4 represents a plan view of the detectors and breakingdevices. Fig. 5 represents an end elevation of the breaking device, andFig. 6 represents an end elevation of the detector devices.

Similar characters designate like parts throughout the several figuresof the drawings.

In the drawings, 10 represents, in dotted lines, a portion of a seriesof bobbins from which the slivers 1 1. are drawn through eyes 12 insuitable detectors such as the plates 13, secured to or forming a partof the members 14, pivoted at 15 to the standard 16 forming a part of orsecured to the frame 17. The frame 17 is provided with an upwardlyextending arm 18 having formed thereon, or secured thereto, at 19, asuitable guideway for the detector plates 13.

The slivers 11 pass from the eyes 12 between the drawing rolls 20, andthen pass from between said drawing rolls, through the 22, secured tothe end of the lever 23 pivoted to the standard 16 at 15, and extendingbeyond said pivoted leverinternediate of said members 14. The eye orslot 21 is provided with an extension in the nature of a narrow slitextending to the edge of the plate forming the breaking device 22. Theend of said lever 23 opposite to the breaking device 22 is provided withoutward projections 24 extending be neath the members 14 so that anydownward movement of either of the members 14 about the pivot 15 willact upon the projections 24 to cause an upward movement of the breakingdevice or plate 22.

On either side of the members 14 are vertical guides 25 extendingupwardly from the frame 17 these guides preventing lateral movement ofsaid members. The detector plates 13 are provided at their lower ends 1ing pivoted to each other at with toes or shouldered projections 26,Which are adapted to be engaged, when a sliver 11 breaks permitting thefall of a detector, by a feeler 27, secured to a shaft 28, about theaxis of which it is oscillated by means of suitable positively drivenmechanism.

hen the detector plates are in the position shown in Fig. 2 the feeler27 is free to oscillate without engaging said plates or performing anyfunction. Should, however, a sliver break and permit the fall of thedetector plate into a lower position, as shown in Fig. 3, the forwardmovement of the feeler 27 will engage with the toe 26 and cause afurther downward movement thereof which will operate through theprojections 24 and the lever 23 to move the breaking plate 22 upwardlyand sever the united slivers passing from the drawing rolls. This is averyi sportant feature as by means of the severing of the slivers atthis particular point no singles are permitted to pass from. the drawingrolls thereby effecting a uniformity of the output of the franc. Thisdevice insures a great saving both to the master and to the operator asthe severed ends are more readily picked up and joined togetherabsolutely preventing any singles in the output while at the same tine amuch better product is assured. I

The feeler 27 extends lengthwise of the frame parallel to the rocl'ershaft 28 to which it is secured by suitable arrr s and is driven bymeans of an arm 30, secured to said shaft 28. To the end of this arm 30is pivoted a twopart connector 31-32, said parts 3132 be- 33 while theouter end of the 11651';.b61 32 is pivoted at 34 to a lever 35 which inturn is pivoted at 36 to a rearwardly extending arm 37 secured to therail or frame 38. The lower end of the lever 35 is connected,by;neans ofthe link 39, to a gear 40 meshing with the gear 41, on the shaft 42 ofone of the drawing rolls. It is obvious from an inspection of thedrawings that as the shaft 42 is continuously rotating a continuousoscillation is imparted to the feeler 27 through the instrumentalitiesjust described.

T o the arm 37, is secured an upwardly extending bracket 43, in which ismounted the controlling rod 44, provided with a groove 45 therein. Thebracket 43 is provided with guideways 46, in which is slidably mountedan inverted U-shaped member 47 the lower concaved portion of whichengages the groove 45 of the controlling rod and prevents lateralmovement thereof. The forked ends of the U-shaped member 47 extenddownwardly to a point just above the twopart connector 31-32 whichoperates, without interference therewitn, to oscillate the feeler 27,when the parts are in their normal position. As soon, however, as thedetector 13 is moved downwardly into the path of the feeler 27 so thatthe oscillation of the feeler 27 is limited and said feeler is preventedfrom moving to the extreme of its movement, the joint in the two-partmember 3132 will be broken to cause these parts to assume the positionshown in dotted lines in Fig. 3 thereby contacting with the lowerextremity of the U-shaped member 47 and lifting it into the positionshown in dotted lines in said figure. This limitation of the movement ofthe feeler 27 is effectedby the lever 23 contacting with thedrawingrolls 20 and preventing, by means of the projections 24, anyfurther downward movement of the pivoted member 14 which carries theprojecting lip 26. It is this lip 26 with which the feeler 27 contactsand which limits the movement thereof.

In order to accomplish the breaking of the joint in the connector 31+32the member 31 is provided with a pin 48 which cooperates with theinclined face 49 of the member 32 when the movement of the rocker shaft28 is restricted, this pin 48 co-acting with the inclined surface 49 tocause the joint to be broken and raised into the position shown in Fig.3 as and for the purpose heretofore described.

Normally the inclined surface 49 is held in contact with the pin 48 andcauses the connector 3132 to remain in fixed relation to each otherduring the oscillation of the arm 30, the strain on said parts 31 32being such as to retain them in this position until the movement of thefeeler 27 is limited by its contact with the lip 26. This normal fixedrelation of the parts 31*32 during the oscillation of the feeler 27 isprovided for by the relative positions of the pivot 33 and the stop pin48, the former being at a higher point than the latter, thereby insuringthe contact between the inclined surface 49 and said stop pin as alreadydescribed.

When the bifurcated or forked member 47 is lifted into the positionshown in dotted lines in Fig. 3 it is withdrawn from contact with thecontroller rod 44 so that said rod may be moved longitudinally thereofto effect a stoppage of the machine. The mechanism for accomplishingthis is shown in Fig. 1. in which 50 and 51 indicate a portion of theusual fast and loose pulleys while 52 is the usual belt fork or shipperdepending from and secured to the shipper rod 53, mounted in suitablebearings in the end frame 54 of the machine and in a second bearingformed in a bracket 55 secured to the top of the frame or side rail 38.By means of a suitable handle 56, secured to said. shipper rod 53, thelatter can be moved, by hand, longitudinally to shift the belt from thefast to the loose pulleys when it is desired to stop the frame manually.The shipper rod 53 is provided with a collar or other annularenlargement 57 which is en- 1 when the bifurcated member 47 is lifted torelease it from engagement with the groove 45 in said controlling rod.This movement of the controlling rod 44 operates through the medium ofthe arm 58 and collar 57 to move the shipper rod 53 and stop the drivingmechanism until the breaks have been mended, when the mechanism is againset in motion by the operator. By means of this mechanism, the movementof all the sets of slivers is stopped when a single is prevented in anyparticular set, thereby preventing the intact sets of slivers fromgaining on the broken set and insuring a uniform product.

The slot or eye 21 on the breaking device I 22 is of such a width as topermit perfect rovmgs to pass from between the drawing rolls throughsaid slot but is sufficiently narrow to prevent knots and lumps frompassing through.

This is a very important feature of the invention as sometimes theroving passes from the drawing rolls knotted up with lumps therein whichare liable to interfere seriously with the operation of the loomiriwhich the product may be used and make imperfect cloth which has tobe sold at a loss. By this device these objections are entirely obviatedfor as soon as a lump or knot in the roving reaches the breaker and isunable to pass through the slot or eye 21 the roving is broken by theknot or lump coming in contact with the rear face of the breaker and assoon as the roving is severed by this means the breaking device 22 willmove upwardl into the position shown in full lines in Fig. 3, owing tothe fact that the opposite end of the lever 23 is heavier than the endof said lever in front of the pivot 15. hen in this position the rearedge of the lever 23 will be in the path of the feeler 27 and will limitits downward movement thereby causing the stopping mechanism to operatein the manner heretofore described. As soon as the frame is stopped inthis manner the operator is obliged to reunite the severed slivers,first removing the objectionable knots or lumps therefrom before hestarts the machine again.

It is believed that from the foregoing the operation of the inventionwill be thoroughly understood without any .further description.
